63263 Visit/Submit website Re-Design

I have a new website ([login to view URL]), but I think the design isn't as good as it CAN be. It's a website traffic and submiting services site. What I want to be done is to make it a site that when someone interested in what I'm selling enters the page will actually stay IN the site and browse it, and eventually, buy. The site is completely developed, everything I could do I did to it, I check the text and all that almost everyday, but I know it can be optimized. Also, I have no logo. I would like to add a flash logo at the head part of the website or something that looks good. It doesn't has to be a complete redesign, I would like it to be a BETTER site. A sales-maker site... Thank you very much.
